The present application'relates to a method and machine for making hairwaving Pads, and it also relatesto the hairwavingpads'` producedthereby. f

In`v my prior application Serial No. 678,162, led June 29, "1933 thereis disclosedsa pad making machine in kwhichastrip of an absorbentmaterial, such as filter paper, annelor felt ,and a `strip ofnonfabsorbent, such, as a non-,permeable, a parchmentized rpaper( and/orfoil, 'are fed substantially continuouslyfrom rolls onopposite sides ofthe assembling machine towarda cen.- trally positioned sewing ,machineunit. If desired a .wiremay be ,fed Withthe wrapper and caused to adherethereto. Y Y v The absorbent material is preferably fed' at such a rateor in such ,widths in the .prefe`rred embodiment that there isasubstantiallygreater area V-of the wrapper-material for eachsection ofthe absorbent material in the i'lnal ,133415, whereby when theabsorbentmaterial ,is vsalturated with liquid and wrapped aroundthehair, itmay be c completely..encompassedbythe wrapper material. y y

.In the preferred construction shownaccording to this prior applicationthe wrapperelements lwere.imprinted. while Istill rbeing fed as acontinuous `strip and Such wrapper, and absorbent strips were not cut tof orrn .suitable strips for the single hair waving pads until theyareadjacent to the 'sewing machine. In this position theywere laid inslightly overlapping position with the 'felt projecting substantiallyfor `Athe major portion of-its area beyond 'the wrapper. The sewingmachine sews'thefabsorbentmaterial and the wrapper material together.`at said overlapped portion to form f the final pad unit.

In another application, Serial MNO. :683,-61-3, filed yAugust 4, 1,933,thereis discloseda,s evqring machine unit l,Witlfi--a.lfiatifle.needle,V permitting the `needle to move*v with the readilytearable wrapper strip. The, strip of Athe .wrapper material is drawnthrough the .machine .and then successively assembled .with ,foil vand.the absorbent material, thefoiland absorbent `mate#` rials being valsofed` continuously fromrollstrans-v versely, toward thea d van cingWrapper strip.

AIn the, preferred embodiment, the wrapper was formedfrom a stripofparchmentor other non permeable paperwhich wasfoldedasit wasjfed.Then-the foil strip was inserted entirely-therebe{ tween and cut,andithensubsequentlythe-abi sorbentv strip was merely Ainserted `between|`the edges of thefolded strip andfthen ywas cut,-the

foil andlabsorbent lmaterialbeing held .fin-their (cruel-262) ,positionby' ,suitable rollers, Vwhile the oating needle/ ofthe sewing' devicesewed Vthe whole together.

After the sewing lwas .completed the advancing Wrapper" strip `was cutltoA form the individual pads, and these individual pads' were imprintedwith suitabletrad'e-marks or legends andthen vauto matic'ally countedand subsequently packcri 7 It'has' beenfound desirable to make a machine10 which wouldbe capableof still additional operations than the machinespecificallyUdescribed above and particularly which would be capable ofYassembling both rthe `Wrapper and absorbenty material, either infolded' condition or in unfolded condition, as desired. c i

In assembling a `folded strip of the wrapper andfolded strip oftheabsorbent it has been .found most suitable to feed the strips'parallelly to each other, with a wrapper being fed ata substantiallylgreater rate Ythan the absorbent. Generally,I it hasbeen founddesirable to feed the absorbent stripintermittently and the wrapperstrip continuously, and then to cut thefab-sorbent strip at intervals tosecurev sections Aof the abv 25 sorbent of a shorter'length, than thecorresponding portion of thewrapper strip to which the absorbent stripisattached.

`After thel absorbent strip; is cut vinto` sections, it is movedinwardly into partially superimposed positionin respect tothe wrapperstrip and the two are sewn together, preferably by .a single threadchain stt'ch,and.preferably by a needle unit which maymove 'with thewrapper during the formation of each stitch so that the wrapper asit isdrawn past the sewing machine will'not tend to be tornby `the needle. Inassembling the `absorbent strip vwith the wrapper striptiti's desirablethat the edge of the Wrapper strip if Ifolded or multiple, be separated,Vso as to permit. the absorbent strip tobe inserted therebetween Vandvit is aparticular feature of the present inventionwherefthe wrapperstrip consistsf a multiplaply of f,0.i1 and paper rmly connected byeJparafnor wax adhesive bond, to

`release said bond sufficiently during the assem- Vide a die which willact upon the wrapper strip to cut out portions thereof in accordancewith a desired shape which is to be obtained.

At the same time, a cutter device may be employed to sever the stripbefore, during or after the die cutting operation.

After the die cutting operation, it has been found most desirable thento emboss, imprint or otherwise mark the wrapper section of theindividual pads with a trade-mark or descriptive legend as may bedesired and after this imprinting or embossing operation. The individualpad units then are counted off in piles of say about fty each, and arecarried by a belt to a place Where they may be packaged and/or otherwisedisposed of.

It is an important feature of the present invention that the successiveoperations of feeding the wrapper and absorbent strips, of folding oneor both of these strips, of cutting the absorbent strip, of assemblingthe cut absorbent stripwith the separated wrapper strip, of cuttingand/or die cutting the wrapper strip, of imprinting and/or embossing andof counting are synchronized so that all these operations Will takeplace at a predetermined interval in respect to each other, and atpredetermined positions.

This invention will appear more clearly from the following detaileddescription when taken in connection with the accompanying drawingsshowing by way of example, preferred embodiments of the inventive idea.

Figures 17a to 17e show the feeding, folding and assembly operations toproduce the construction l of Figure 17, Figure 17a being a top View;Figure 17h being a fragmentary side sectional View on enlarged'scale, onthe line l'lb l'lbl of Figure 17a'I and Figure 17e being a diagrammaticcross sectional View on enlarged scale indicating the insertion of thesevered absorbent sections into the folded wrapper strip.

Figures 18a, and 13b illustrate the construction of the pad according toFigure 18; Figure 18a being a side elevation view and Figure 18h being adiagrammatic side sectional view illustrating the assembly of the annelsections with the wrapper strip.

Referring particularly to Figures 16 to 18, the wrapper material A andthe flannel of felt material B are fed forwardly to the left, asindicated by the arrows 25.

The absorbent material B' may consist of flannel, doubled so that itsopening will be adjacent the wrapper, as indicated in Figure 16, so thatits opening may be away from the wrapper, as indicated in Figure 17, orit may consist of an unfolded sheet of material as indicated in Figure18.

Strips of filter paper and/or strips of felt may also be utilized aloneor in combination with other absorbent materials as indicated in Figures16 and 17.

The wrapper strip A on the other hand may consist of a single strip ofmaterial, as indicated in Figure 16, or it may be folded to enclose afoil strip C as indicated in Figure 17.

In Figure 18 the wrapper D preferably consists'of a strip of foil andpaper paraflined or waxed together, which may be subjected to the actionof a heater or separator element E to permit a separation of the edgesand insertion of the absorbent Vmaterial at the proper position where itmay be sewed in. location during subsequent operations of the machine.

Referring to Figure 1 the guide for the wrapper strip A is indicated atF while the guide for the nal strip is indicated'at G.

It is desirable in making the pads, as indicated at the left of Figure16 and in Figure 12 that the flannel strip be of substantially lesserlength than the wrapper strip' to which it is sewn and for this reasonit is desirable to have an intermittent feed 26 of the flannel with asubstantially continuous feed 25 of the wrapper strip A.

Referring to Figure 1, the continuous feed of the wrapper strip A isobtained by the continuous rollers I-I which are provided with anadjustment S enabling regulation of the rate of feed, while theintermittent feed is achieved by means of the intermittent mutilatedrollers I.

The rollers H continuously draw the wrapper sheet A through the sewingmachine J and the intermittent rollers I` intermittently advance thepersheet A,.so that thesewingmachinewill form a continuousrunningfstitch through the superimposedposition,andrpermanently attachthe absorbent material. to the maingwrapper strip.

' The inserter device AL .preferably ,works in synchronism with the'pickup device V which takes the v form ofl a. mutilated roller,releasing the multi-ply wrapper. strip atitsedge adjacent the 1absorbent ,strip when V,the inserter device L acts to insert Athe`folded .and cut flannel therebetween.; and gripping the cut absorbentstrip in position in the continuous wrapperstripso that assembly willbe-advanced to the sewing machine .with assurance that the wrapperandcutabsorbent strips will be sewn togetherqn proper position.

After the cut flannel sections have -been sewn intoposition bythe'sewing machine'J. and have passed the main `feed rollersH, theassembly passes over the tensioning device N. 'The device N lassuresthat a satisfactory tension will be maintained at all'times on the stripin being fed to the die cutterO-Qso thatit will not be buckled `ordoubled .up=in the intervals' when the clamp rollerP holds'theadvancingstrip A against further kmovement until the 4die' cutter Ohas completed .its operation upon the previous pad section. i

After the. die cutting operation, the severed .sheets yare then pickedup by the printing machine Q where they are imprintedand/or embossed andthey are vthen passedlonto the counter and conveyor device R.

j The main shaft S shown in Figure 1 will synchronize Vthe various-portions of the machine and assure that thefeeding, sewing, imprintingand cutting operations ,will take place in synchronism in thepredetermined `time intervals in respect to each other.vv

' Asshown-in Figure 16,the fold21 of afolded cut` flannel section Tmayextend outwardly from the single ormulti-ply wrapper strip A'or multior. singlezply section T maybe inserted between the. plies of thewrapper. strip A as indicated in Figures 17 and 18.l r r :As soon v'asthe sections Tareinserted or positioned in slightly. overlappingposition as indicated at 28', in Figs. 16 lto 18, inclusive, with theaid of the device .(see Figs.l'16e,17cand 18h) theintermittent rolls:;V(seeFigs. .v1 and 2) will seize the overlapping'portions 'of the.absorbent section T and the wrapper sheet A andiholdthem in positionwhile the wrapper section is being advanced to the sewingmachine J.

In Figures 16 to 18,'.afterthe sewing-Operation, vthe'cutting device atthe position O will sever the wrapper strip which -willfbe imprintedand/ or embossed at the position.Q.*

After the imprinting and embossingthe pad units will be counted Vofi' inrpiles ofy say twentyfive .upon the. conveyor device or belt `indicatedat the position'R.. l Referring'to Figuresj'l, 2.and 3,1the machine ofthe present 'invention is provided-witha main table suppo-rt 29 havinglegs -30 onv thejtable 30' machine. As indicated-best inFigures-3andci,l

the bed. plate V3| is'iprovided with-side anges 132' whichextend^thelength of the-machine tablel29;

ySupportedon-the bed plate 3| at theright end :drives the pinion|42`andthe meshing gears 43 and 44.

,'Thegears-43and 44.(se7e Figs. 1 to 3) connected to drive'the-mutilatedfeed rollers 46 and 41 which rollers are cut out as indicated at 48, 49y(see Fig- 1Ire2) to-cause an intermittent feed of the foldedflannelsheet into .the guide G.

The v.wrapper strip which is fed through the guide F, Vpasses on to theportion 50 of the main table V where it is fed in parallelism with theflannel strip being fedover the runway G, the paper or wrapper strip Fbeing engaged by feed rollers H.

vIt will befnoted that Ythe runway G is provided with side elevations 5|while the runway F is provided with side ridges 52 respectively 'toguide the flannel or absorbent stripand the parchment or foil strip intothe table V at 50.

The cutter device K (see Figures 1, v2 and 3) is provided with `a blade15 carried by the reciprocating member 16- which is mounted on the shaftis fixed at its right end in the eye 19Iat the upper4 end of the lever8|) which lever at its lower end is pivotally connected as at 8| to theend of theilinkZ (see Figure 3). f l

The other end of the link 82 is provided with anelongated ey-e83 whichis received upon the main drive shaft S and which shaft carries vthe cam85 cooperating with the roller 86 on the link 82. 'The springvvl whichis connected at 88' to the link82 and at 89 to the base plate 3|,biasesthe link 82 to the right-as shown in Fig. 3 to maintain said roller 86in contact with the caml 85 at all times.

In the position shown in Figures 2 and 3, the cutter K is cutting thefolded or multi-ply flannel or single ply-felt strip as it isintermittently fed 45 end of the table U at 9|J and sever the absorbentstrip B into sections T `(see Figs. 16 to 18).

'I'he pressure of the rolls 46, 41 may be varied by the arrangementshown best in Figures 1, 2 and 3.

The upper roller 46 together with its gear 44, is mounted in a clevis 9|(see Figs. 1,. 2 and 6a) having the side arms .92, the arms lof saidclevis being provided withbearings, 93, 93 for the shaft of said upperfeed'roller 46. The clevis 9| is pivotally mounted on the shaft 94'which is provided with the bearing 95 on the side frame member 35. 'I'heupper roller 46 is normally pressed against the lower roller 41 by thespring 96 reacting against the forwardly eX- tending nger 91 from saidclevis arm 92 (see Fig. V3) `The spring 96 encircles the pin 9B which ismounted upon thebearing member 18 for `the shaft 11. The nuts |00 enableadjustment of the tension on the spring96.` i i Afterithe foldedfiannelstrip has been cut the cutportionis left upon the portion of the table.U (seeFig. i1.) .whereit is in positionto, be

acted upon by the pusher or inserter element L (see Figures 1, 2 and 4).

The pusher element 2 includes a diverging plate III (see Fig. l) whichisV provided with a downwardly extending bracket H2 (see-Fig. 4) theguide member I I3 and the reciprocating shaft ||4 at ||5 and H6,respectively.

The guide shaft H3 extends through the guide opening ||1 in the upwardlyextending flange IIB of the base ||9 bolted as at |20 to the base plate3 I. The shaft |4 extends through the base plate I9 and is provided atits right end with the follow roller |2| which cooperates with the cam|22 and mounted upon the shaft S.

The rod I I4 is normally biased to the right, as shown in Figure 4, bythe coil spring |23 which reacts at one side against the wall |24 of thebase structure H9 and at the other end against the collar |25 fixed at|26 upon the rod or shaft |I4.

In operation, when the recess |21 of the cam |22 comes opposite theroller |2I, the plate III will move to push the felt or flannel sectionT into position in respect to the folded wrapper strip A (see also Fig.16e, 17o and 18D).

If the wrapper strip is composed of a sheet of paper and a sheet of foilparaiined together, the edge of the wrapper strip, may be subjected tothe action of the separator element E which includes the casing |36having a heating coil therein and electric connections |31 to separatethe edges for insertion of the cut sections T (see Fig. 5)

The heating coil is provided with a n extension |36 which projectsbetween the edges of the adhering foil and paper strips and appliessufficient heat to melt the paraiiin or wax after separation by theelement E, the edges of the wrapper strip A will be held apart so thatthe out sections T of the flannel strip may be conveniently insertedthereinto by the device M (see Fig. 4).

The wrapper strip A in the meanwhile is being drawn substantiallycontinuously over the guide F and onto the table U at 56 (see Fig. 1) bythe feed rollers H which are positioned beyond the sewing machine J.

Th-ese feed rollers are best shown in Figures l, 2, 6 and 8.

Referring to these figures, it will be noted that the feed rollers Hinclude an upper roller I4I and lower roller |42 having respectively theshafts |43 The lower roller shaft |44 has bearings` at |46 and |46 inthe frame structure |41.

The shaft |43 is connected to the driving'gear |49, while the shaft |44is connected to the driving gear |56.

The rollers |4| and |42 are preferably provided with a rubber surfacingand the pressure between them may be varied by providing the upperroller |4| with a bearing yoke I5| which has adjustable slide members|52 and |53 carrying the shaft |43. Said members |52 and |53 fittinginto recesses or vertical slots in the members |45 and The pressurebetween the rollers |4I and |42 may be varied by the adjusting screw|55, the lower end |56 of which contacts with the flattened portion |51at the top of the yoke I5I.

The scr-ew |55 is carried by the plate |59 which is bolted at |60 (seeFig. 7) to the upwardly extending ange |6| from the transverse member|62 of frame |41. The member |62 carries Ythe structures |45, receivingfor the slide members |52 of the yoke |5|. n Y

On the same shaft as the gear |50 are provided a series of differentdiameter gears |65, |66, l|61 (see Fig. 6) which are xed in position bythe `collar|68 and the `pin |69. These gearsy |65 to |61 may beselectively driven by the gear |1| to control the rate of feed ofthewrapper strip between the main feed rollers I4I and |42.

Ihe gear |1| is carried on the arm I 12 which is provided with an endilange |13 having the eye |14 pivotally mounted on the sleeve |15 on theshaft |16. 1

The shaft |16 drives the elongated gear |18 which meshes with and drivesthe intermediate adjustable gear |1|.

As indicated best in Figures 7 and 8, the eye |14 is Vsplit and isprovided with anges |19 and |80 which are drawn together by the bolt IBIto clamp tightly the-xed sleeve |15.

By loosening the bolt |8I it is possible to shift the gear I1| bothrotatably and longitudinally on the sleeve |15 to enable engagement ofthe gear I1| with the different driving gears |65, |66, |61 as may bedesired.

The arm. |13 and the gear |16 are each of such length as to giveassurance that the gear |1| will always meshwith and be driven by thegear |18. The gear |18 is driven by the shaft |16 which bears in thesleeve |15, |82, supported on the frame structure |10 attached to thebed plate 3|.

The spiral gear |83 is fixed on the shaft |16 by the collar |84 andthepin |85 and is driven by the corresponding gear |86' attached to themain drive shaft S. i

Referring to Figs. 6 to 8 and also Figures 1 and 2, it is apparent thatby relatively simple adjustment, namely, by loosening the bolt |8| andadjusting the gear |1| to mesh with the desired gear |65, |66, |61, itis possible to regulate the speed of feed of vthe wrapper strip wherebythe length of wrapper relatively to the length of the section T of theabsorbent strip may be varied.

After the section T has been cut and inserted by the devices L and M inthe continuously feeding Wrapper strip A, it is picked up by themutilated feed rollers V (see Figs. 1, 2 and 4). These mutilated rollersconsist of an upper roller 200 and a lower roller 20|, the upper rollerbeing connected to a shaft 202 which bears. at 203 and 264 in the yoke265 extending upwardly from the frame H9.

The lower roller v20| turns upon a shaft 206 having bearings in theflange |I8 and at 2|6 in the frame I I9 and driven by an intermediategear 2I1 between the gears 209 and 2|0 (see Fig. 6).

The upper roller 200 (see Figs. 1, 2 and 4) is driven by the gear 209 onthe end of the shaft 202 which in turn is driven through the gear 2 I 0from the gear 2 I on the shaft 2 I2 (see also Fig. 3).

After the annel or felt strip B has been cut into the sections T, asindicated in Figures 16 to 18, and inserted between the opening device Mbetween the plies of the wrapper strip A, as indicated in Figure 4, thewrapper stripA together with the absorbent section T after it has beenpicked up by the full diameter portion of the rollers 200 and 20|, willbe moved up to the sewing machine J.

In connection with the sewing machine J, (see Figs. 1, 2, 8a and 8b) inView of the fact the wrapper strip A is being drawn therethrough at arelatively high rate by the feed rollers H (see Figs. `7,8`and 9,) ithas been found necessary to
